This week I got one that works very well as a video.\r\n\r\nThe problem was trying to index into a vector with a vector of ones and zeros. While this vector was all ones and zeros, it was still considered a double precision variable. I use DBSTOP to help figure out this situation. Because I was debugging this live, I made some unscripted errors that made this video a good capturing of the real confusion that comes when debugging and how to overcome those challenges.\r\n<div><div class=\"row\"><div class=\"col-xs-12 containing-block\"><div class=\"bc-outer-container add_margin_20\"><videoplayer><div class=\"video-js-container\"><video data-video-id=\"3877438011001\" data-video-category=\"blog\" data-autostart=\"false\" data-account=\"62009828001\" data-omniture-account=\"mathwgbl\" data-player=\"rJ9XCz2Sx\" data-embed=\"default\" id=\"mathworks-brightcove-player\" class=\"video-js\" controls><\/video><script src=\"\/\/players.brightcove.net\/62009828001\/rJ9XCz2Sx_default\/index.min.js\"><\/script><script>if (typeof(playerLoaded) === 'undefined') {var playerLoaded = false;}(function isVideojsDefined() {if (typeof(videojs) !== 'undefined') {videojs(\"mathworks-brightcove-player\").on('loadedmetadata', function() {playerLoaded = true;});} else {setTimeout(isVideojsDefined, 10);}})();<\/script><\/div><\/videoplayer><\/div><\/div><\/div><\/div>\r\nIf you want more about debugging, look at a recent <a href=\"https:\/\/blogs.mathworks.com\/community\/2008\/11\/17\/adding-debugging-code-without-changing-your-code\/\">MATLAB desktop blog post<\/a> on the subject also.","protected":false},"excerpt":{"rendered":"<div class=\"thumbnail thumbnail_asset asset_overlay video\"><a href=\"https:\/\/blogs.mathworks.com\/videos\/2008\/11\/20\/video-tutorial-debugging-a-logical-indexing-problem\/?dir=autoplay\"><img decoding=\"async\" src=\"https:\/\/cf-images.us-east-1.prod.boltdns.net\/v1\/static\/62009828001\/8f3b6be0-45f1-439d-bc0c-388da7df2c59\/5ff0a16f-69a0-4c26-9478-9afba903af1b\/160x90\/match\/image.jpg\" onError=\"this.style.display ='none';\"\/>\n      <div class=\"overlay_container\">\n      <span class=\"icon-video icon_color_null\"><time class=\"video_length\">4:48<\/time><\/span>\n      <\/div>\n      <\/a><\/div><p>I love getting well formed question and challenges from fellow MATLAB users.
